<h2 id="dbase/db2array">db2array</h2>
<div class="headline">Convert tseries database entries to numeric array</div>

<h4 id="syntax">Syntax</h4>
<pre><code>[X,Incl,Range] = db2array(D)
[X,Incl,Range] = db2array(D,List)
[X,Incl,Range] = db2array(D,List,Range)</code></pre>
<h4 id="input-arguments">Input arguments</h4>
<ul>
<li><p><code>D</code> [ struct ] - Input database with tseries objects that will be converted to a numeric array.</p></li>
<li><p><code>List</code> [ char | cellstr ] - List of tseries names that will be converted to a numeric array; if not specified, all tseries entries found in the input database, <code>D</code>, will be included in the output arrays, <code>X</code>.</p></li>
<li><p><code>Range</code> [ numeric | <code>Inf</code> ] - Date range; <code>Inf</code> means a range from the very first non-NaN observation to the very last non-NaN observation.</p></li>
</ul>
<h4 id="output-arguments">Output arguments</h4>
<ul>
<li><p><code>X</code> [ numeric ] - Numeric array with observations from individual tseries objects in columns.</p></li>
<li><p><code>Incl</code> [ cellstr ] - List of tseries names that have been actually found in the database.</p></li>
<li><p><code>Range</code> [ numeric ] - Date range actually used; this output argument is useful when the input argument <code>Range</code> is missing or <code>Inf</code>.</p></li>
</ul>
<h4 id="description">Description</h4>
<p>The output array, <code>X</code>, is always NPer-by-NList-by-NAlt, where NPer is the length of the <code>Range</code> (the number of periods), NList is the number of tseries included in the <code>List</code>, and NAlt is the maximum number of columns that any of the tseries included in the <code>List</code> have.</p>
<p>All tseries with more than one dimension (i.e. with more than one column) are always expanded along 3rd dimension only. For instance, a 10-by-2-by-3 tseries will occupy a 10-by-1-by-6 space in <code>X</code> at its respective location.</p>
